Other Professional Experience

July 1997 to August 1999. Reservoir Specialist and Technology Champion (Special Projects) at YPF, S.A., The largest domestic and international Argentine oil company. The work included the technical leadership of a reservoir geophysics group aimed at assisting in the development of producing reservoirs. This group was responsible for the petrophysical evaluation of well logs and cores, interpretation and inversion post-stack 3-D seismic data, outcrop studies, geostatistics, data integration, and well completion and perforation practices. In so doing, a successful integrative methodology was developed for the detection, delineation, and petrophysical evaluation of thin sands. Several wells were drilled and evaluated by different asset teams as a result of our recommendations.

November 1991 to June 1997. Research Scientist at Schlumberger-Doll Research, Ridgefield, Connecticut, USA. The work involved the numerical simulation of electromagnetic propagation in rock formations via integral and partial differential equations with applications to the deep probing of rock formations, induction logging and cross-well electromagnetic tomography. A large part of this effort involved the development and field testing of mathematical and physical procedures for the inference of physical properties of rocks from electromagnetic measurements, including the interpretation of data acquired in producing hydrocarbon reservoirs. Some of this work was adapted to the numerical simulation of elastic wave scattering in heterogeneous rock formations. On a different project, work was performed to sense and numerically simulate fluid movements (e.g. water-oil contacts) in producing hydrocarbon reservoirs by means of permanently deployed electric and pressure sensors. This latter subject included the development of numerical methods for the inference of permeability variations in reservoirs jointly from dynamic in-situ pressure and electrical resistivity measurements.

September 1991 to October 1991. Research Scientist at Lawrence Berkeley Laboratory of the University of California, Berkeley. The work involved the development of computer codes for the imaging and inversion of electrical properties of the earth from natural and controlled-source surface electromagnetic measurements.

June 1991 to July 1991. Geophysical Consultant for the company Electromagnetics Instruments, Inc., of El Cerrito, CA. During this time, field, technical and interpretative assistance was provided to the Italian exploration company, Geoinvest of Piacenza, in the different phases of an exploration project aimed at evaluating the hydrocarbon potential of mountainous geological provinces in Umbria and Basilicata, Italy.

January 1987 to May 1991. Graduate Student Research Assistant, University of California, Berkeley, CA. Research activities included the development of new procedures for the sampling, processing and interpretation of electromagnetic data acquired in the form of one- and two-dimensional surface arrays.

January 1989 to June 1989. Consultant Research Engineer for the company Mintech Geosciences of Concord, CA., on the application and evaluation of the EMAP (Electromagnetic Array Profiling) technique in the exploration of geothermal reservoirs in Japan.

July 1987 to August 1987. Consultant Engineer for the company Electromagnetic Instruments, Inc., (EMI) of El Cerrito, CA., on the development of a magnetotelluric data acquisition system.

January 1986 to December 1986. Graduate Student Research Assistant, Lawrence Berkeley Laboratory, CA. Duties included (a) Processing and three-dimensional interpretation of a electromagnetic data set for the geologic evaluation of the Long Valley Caldera, Mammoth, CA.

January 1984 to December 1985. Graduate Student Research Assistant. Geomagnetics Research Laboratory, The University of Texas at Austin. Research activities included analytical and numerical studies in electromagnetic theory concerning a novel adaptation of the magnetotelluric method known as Electromagnetic Array Profiling (EMAP).

December 1982 to August 1983. Research Engineer, Department of Applied Geophysics of the Instituto Mexicano del Petroleo (Mexican Institute for Petroleum). Tasks included the development of computer algorithms for the processing and interpretation of gravity, magnetic, and seismic data.

December 1982 to March 1983. Consultant Engineer in charge of the interpretation of Schlumberger DC resistivity soundings for groundwater exploration and dam foundation studies.
